Damsel Adult by Seabrooke

“Because they’re predatory, both damselflies and dragonflies have excellent eyesight. They have a pair of large compound eyes that are their primary means of detecting prey, but also several occelli across their “forehead” that they use for sensing small changes in light and dark, which helps them to orient upwards. The eyes are another useful feature to separate damsels from dragons – the compound eyes of the latter meet at the top of the head, while those of damselflies are usually widely separated. The eyes are also very important for avoiding predators.”
